The Research On The High School Students' Cognitive Level Of Solid Geometry In Minority Areas

The related problems in space geometry is one of the important contents to learn in high school mathematics solid geometry.It plays a crucial role in developing students' sense of spacecultivating students' ability of spatial imagination and consolidating students' logical thinking ability.In the past year's college entrance examination,this part is a key and difficult part.The examination questions mainly include choices,fill in the blanks and answer questions,and all examined subjects are ingenious,flexible,novel and unique.Linxia Hui Autonomous Prefecture is the Northwest Hui and Dongxiang and other Muslim ethnic enclaves,because of ethnic customs and habits,learning quality,economic conditions and geographical environment and other factors,the students in the learning content of spatial geometry in the cognitive level,the level of understanding,there are some problems on the level this,of the minority teachers also put forward the corresponding requirements.According to the survey,we found that the cognition level of the two school students in the ethnic minority area is relatively low,and the number of students who focus on the low cognitive level is large.The cognitive level of the students' learning space geometry is different in gender,and on the whole,the cognitive level of the girls is higher than that of the boys.The cognitive level of the learning space geometry of the students in different grades is also different,and the cognitive level of the students in the third class is higher than that of the sophomore students.There are differences in the cognitive level of the learning space geometry of the Hui,Han,and Dongxiang students.The status of high school students in Linxia,Guanghe County,based on the cognitive level of body geometry,put forward to improve the national high school students some learning strategies of the cognitive level of space geometry:First,in the instructional design highlights the value of space geometry in real life;Two,pay attention to their own ability,improving the teaching methods,pay attention to the cognitive characteristics of students;Three,care for the growth of children and children's learning;Four,understanding the essence of learning,setting goals and eliminating cognitive puzzles.
